AM v SSWP (IB)
Incapacity benefit (IB) - advance claim - incapacity benefit in youth
Decision in brief
Three-month period from which claimant must be entitled begins on the day the claim is determined, not the earlier date on which the claim is received - late appeal where both any time revision and official error supersession refused - appeal can be made against official error supersession decision and appeal time limit runs from date of that decision
